Abstract
A touch panel input device includes layers A and B. Layer A includes a first transparent film (11), a first transparent resistive film (12), a second transparent film (13), a second transparent resistive film (14), and first dot spacers (15). Layer B includes a third transparent resistive film (16), a fourth transparent resistive film (17), a glass substrate (18), and second dot spacers (19). When the device is operated by a finger, the device detects a contact state of the transparent resistive films in layer A and a non-contact state of the transparent resistive films in layer B. When the device is operated by a finger, the device detects a contact state of the transparent resistive films in layer A and a contact state of the transparent resistive films in layer B. Regardless of the input mode, information of a position thus inputted can be detected. The touch panel input device detects, regardless of the input mode to use a pen or a finger, information of a position inputted by a pen or by a finger.
Description
The present invention relates to a touch panel input device, and more particularly, to a touch panel input device which is provided in a display portion including a Liquid Crystal Device (LCD), and transmits a coordinate signal using a position change caused by pressing with a finger (fingertip), a pen, or the like or a position change associated with content displayed on the display portion and to which a device connected to the touch panel input device is input with the coordinate signal thus transmitted.
The prior art touch panel input device comprises a transparent resistive touch panel. Fig. 1 shows in cross-section a touch plate structure using a prior art transparent resistive film 500.
The touch panel 500 shown in fig. 1 includes a transparent film 51, a first transparent protective film 52, a second transparent resistive film 53, a glass substrate 54, and dot spacers 55 disposed at fixed intervals on an upper surface of the second transparent resistive film 53.
The transparent film 51 includes a flexible transparent film member constituting one surface portion of the touch panel 500. The film 51 includes, for example, a transparent plastic film such as polyethylene terephthalate (PET). The film 51 has flexibility that is easily bent or easily changes its shape when pressed by a finger or a pen.
The first transparent resistive film 52 is made of, for example, Indium Tin Oxide (ITO) or SnO2The transparent conductive film is produced. The film 52 is entirely disposed on the lower surface of the transparent film 51 and has an almost uniform thickness. When the film 51 is pushed by a finger, the film 52 is bent and deformed together with the film 51.
The second transparent resistive film 53 includes a transparent conductive film made of the same material as described above, similarly to the first transparent resistive film 52. The thin film 53 is entirely disposed on the upper surface of the glass substrate 54 and has a nearly uniform thickness, which will be described later.
A glass substrate 54 forms the bottom of the contact plate. A thin film 53 having a uniform thickness is entirely provided on the upper surface of the glass substrate 54.
The dot spacers 55 prevent the first transparent resistive film 52 on the transparent film 51 from contacting the second transparent resistive film 53 disposed on the glass substrate 54 in the non-input state of the panel 500. Further, the density of the dot spacers 55 determines the value of the pressure with which the transparent resistive film 52 is brought into contact with the transparent resistive film 53.
Fig. 2 illustrates in cross-section a state of a touch pad 500 of a prior art transparent resistive film that presses the touch pad using a touch pad pen or a user's fingertip.
When the user presses the transparent film 51 on the upper surface of the touch panel 500 with his or her finger or pen, the films 51 and 52 assume a curved state as shown in fig. 2.
The thin film 51 on the upper surface of the touch panel 500 is bent by the pressing of the pen or the fingertip, and the first transparent resistive film 52 is brought into contact with the second transparent resistive film 53. The films 52 and 53 are set in an electrically on state. By communicating this on state, the touch plate 500 detects a pressing event on the membrane 51.
FIG. 3 illustrates the structure of a sensor for reading an input coordinate location on a touch pad using a prior art transparent resistive film. The position sensor reads out a pair of coordinates (input coordinates) of the contact point between the films 52 and 53.
The input coordinate sensor shown in fig. 3 includes a first transparent resistive film 601, a second transparent resistive film 602, a first resistor 603 roughly shown on the first film 601, a second resistor 604 roughly shown on the second film 602, analog switches 605 to 608, and analog/digital (a/D) converters 609 and 610.
Although each of the resistors 603 and 604 includes a resistor having a general outer shape shown in fig. 3, the resistor actually has a planar shape, i.e., a resistive film similar to the first and second transparent resistive films 601.
The first resistor 603 (first transparent resistive film 601) has two electrodes connected to analog switches 605 and 606, respectively. Switches 605 and 606 are coupled to supply voltage V and ground, respectively.
The second resistor 604 (second transparent resistive film 602) includes two electrodes linked to analog switches 607 and 608, respectively. Connected to the switches 607 and 608 are a supply voltage V and ground, respectively.
In fig. 3, first and second transparent resistive films 601 and 602 are fixed or layered to each other so that electrodes 605 and 606 of film 601 are perpendicular to electrodes 607 and 608 of film 602. The first and second electrodes 603 and 604 are coupled to a/D converters 609 and 610, respectively.
The operation of reading out the contact points, i.e., a pair of coordinates associated with the actual pressing on the touch panel, will be described below with reference to the input coordinate reading circuit shown in fig. 3. Assuming that a fingertip or a pen is used to press the touch panel 500 at a certain position of the transparent film 51 as shown in fig. 2, for example, the upper film 52 and the lower film 53 are in contact with each other at the pressed position.
Fig. 4 shows a first structural state of the input coordinate sensor, in which the touch pad is in this state
The state shown in fig. 2. When the user presses a specific point on the touch plate in the state shown in fig. 4, the sensor conducts a control operation to drive its switch into a subsequent state.
As a result of the switching control operation, a linear potential distribution ranging from the voltage V (volts) to 0 (volts) is formed in the direction indicated by the arrow mark a shown in fig. 4.
In fig. 4, an arrow mark b specifies a point (which will be referred to as a "contact point" hereinafter) at which the first and second transparent resistive films 601 and 602 come into contact with each other. By reading out the value indicated by the a/D converter 609 in this state, the potential at the contact point indicated by the arrow mark b on the second resistor 604 can be detected. Since a linear potential distribution ranging from the voltage V (volt) to 0 (volt) is formed on the second resistor 604, the obtained potential describes the distance to the electrode c in the direction of the arrow mark a. When the direction is aligned with an axis of the system, the value obtained represents an X-coordinate value.
Fig. 5 shows a second configuration state of the input coordinate sensor in relation to the touch pad state shown in fig. 2. In response to pressing a specific point of the touch plate in the state of fig. 4, the sensor controls its switch to enter the next state.
As shown in fig. 5, the control operation of the switch results in that the linear potential is arranged to be linearly distributed over the first resistor 603 from the voltage V (volt) to 0 (volt) in the direction indicated by the arrow mark d.
In fig. 5, an arrow mark b indicates a point (contact) between the first and second transparent resistive films 601 and 602. By reading out a value generated by the a/D converter 610 in this state, the potential at the contact point indicated by the arrow mark b on the first resistor 603 can be detected. In addition, distributed over the first resistor 603 is a linear potential arranged from a voltage V (volt) to 0 (volt), which represents the distance of the point to the electrode e in the direction of the arrow mark d. By aligning the direction to the y-axis of the coordinate system, the value obtained represents a y-coordinate value.
In the related art touch panel using the transparent resistive film, the x and y coordinates of a point touched or pressed with a pen or a fingertip can be read by the operations shown in fig. 4 and 5.
Fig. 6A and 6B show a related art transparent resistive film type touch panel in a sectional view. When the dot spacers 55 are arranged at a smaller pitch as shown in fig. 6A, the distance (an area associated with pressing on the touch panel) between the support points (dot spacers) of the films 51 and 52 being bent is reduced. That is, a strong pressure is required to bring the first and second transparent resistive films 52 and 53 into contact with each other. When the dot spacers 55 are arranged at a larger pitch as shown in fig. 6B, the distance (an area corresponding to the pressing on the touch panel) between the plurality of support points (dot spacers) of the pressed films 51 and 52 is enlarged. This indicates that only a relatively weak pressure is required for the membrane 52 to contact the second membrane 52.
As described above, in the touch panel using the related art transparent resistive film, the load required to establish a contact state between the upper and lower transparent resistive films can be adjusted according to the interval of the dot spacers.
For example, in a touch panel using a pen exclusively, the interval of dot spacers is relatively small, so that strong pressure is required to bring the upper and lower films into contact with each other. In operation, even when a certain portion of a user such as a palm touches the touch panel, for example, in addition to the pen, erroneous operation is not liable to occur. I.e. the palm is softer than the pen and therefore contacts the touch plate (transparent film) through a wider area. The load it exerts on the contact plate is not distributed over a point but over an area in a distributed manner. Therefore, the load is relatively weak and it is not easy to bring the upper transparent resistive film and the lower transparent resistive film into a contact state. In this way, the touch plate can continue normal operation without error.
In a touch panel dedicated to a finger, the dot spacers are relatively widely spaced. That is, only a less strong pressure is required to bring the upper and lower films into contact with each other. As described above, finger input is soft and its loading is distributed as compared to using pen input. Therefore, in order to read the contact state between the upper and lower transparent resistive films under a weak pressure of a finger, the dot spacers are disposed at a relatively wide pitch.
However, in the touch panel using the transparent resistive film shown in the prior art example, dot spacers are arranged at a medium pitch so that the touch panel can use both a pen and a finger. Therefore, in the pen input mode, when a part of the hand unintentionally touches the touch panel, an erroneous operation is easily generated. Since the pitch of the dot spacers is smaller than that of a touch panel using a finger, a high finger pressure is required for recognizing an input operation.
It is therefore an object of the present invention to provide a touch pad input device capable of reading input operations using a pen and a finger.
According to the present invention, there is provided a touch panel input device including a first touch panel and a second touch panel, the first touch panel being laminated to the second touch panel.
According to the present invention, the first touch pad includes a first transparent film, a second transparent film, a first transparent resistive film disposed on a lower surface of the first transparent film, a second transparent resistive film disposed on an upper surface of the second transparent film, and a plurality of first dot spacers disposed between the first and second transparent resistive films, the first transparent resistive film being opposite to the second transparent resistive film. Preferably, the plurality of dot spacers are disposed between the first and second transparent resistive films at equal intervals.
According to the present invention, the second touch pad includes a third transparent resistive film disposed on a lower surface of the second transparent film, a glass substrate, a fourth transparent resistive film disposed on an upper surface of the glass substrate, the third transparent resistive film being opposite to the fourth transparent resistive film, and a plurality of second dot spacers disposed between the third and fourth transparent resistive films at equal intervals.
According to the present invention, the second touch pad includes a third transparent film, a third transparent resistive film disposed on a lower surface of the third transparent film, a glass substrate, a fourth transparent resistive film disposed on an upper surface of the glass substrate, the third transparent resistive film being opposite to the fourth transparent resistive film, and a plurality of second dot spacers disposed between the third and fourth transparent resistive films at equal intervals.
According to the present invention, the first dot spacers are arranged at a pitch wider than that of the second dot spacers.
According to the invention, the device further comprises a touch pad controller for controlling the first and second touch pads. The controller includes a determination device for determining that an input operation has been performed by a finger or a pen based on a contact state between the first and second transparent resistive films of the first touch pad and a contact state between the third and fourth transparent resistive films of the second touch pad.
According to the present invention, the determining means determines that the input operation is performed by a fingertip when the first and second transparent resistive films are in a contact state and the third and fourth transparent resistive films are in a non-contact state. The determining means determines that the input operation is performed by a pen when the first and second transparent resistive films are in a contact state and the third and fourth transparent resistive films are in a contact state.
According to the present invention, there is provided a touch panel input device whose structure includes two touch panels attached to each other, thereby enhancing good usability as a touch panel for a finger and a touch panel for a pen.

Embodiments of the touch pad input device of the present invention will be described in detail below with reference to the accompanying drawings. Fig. 7 to 19 show various embodiments of a touch pad input device according to the present invention.
First embodiment
Fig. 7 is a sectional view showing the configuration of the first embodiment of the touch panel input device according to the present invention. As shown in fig. 7, the first embodiment of the touch pad input device 100 mainly comprises two layers, i.e. the first touch pad is layer a and the second touch pad is layer B.
The layer a disposed on the upper side in fig. 7 includes, in the downstream direction, a first transparent film 11, a first transparent resistive film 12, a second transparent resistive film 13, a second transparent film 14, and a first dot spacer 15.
The layer B arranged on the lower side of fig. 7 comprises, in the downstream direction, a third transparent resistive film 16, a fourth transparent resistive film 17, a glass substrate 18 and second dot spacers 19.
As best shown in fig. 7, the density of the first dot spacers 15 is two times or more higher than that of the second dot spacers 19. However, as the effect obtained by the present invention, the present invention includes a case where the density of the spacers 19 is equal to or less than the density of the spacers 15.
The first transparent film 11 forms one surface of the touch panel input device 100 and includes a plastic resin film such as polyethylene terephthalate (PET) as one prior art example. The membrane 11 is flexible so as to be able to bend easily in response to the pressure of the user's finger.
The first transparent resistive film 12 is, for example, ITO or SnO2The transparent conductive film of (1). The film 52 is entirely disposed on the lower surface of the first transparent film 11 and has an almost uniform thickness. When the film 11 is pressed, the film 12 is bent together with the film 11.
The second transparent resistive film 13 includes a transparent conductive film of the same material, similar to the film 12. The film 12 is disposed entirely on the upper surface of the second transparent film 14.
The second transparent film 54 is provided entirely on the film 14 as the bottom portion of the layer a, and the second transparent resistive film 13 is formed with an almost uniform thickness.
The first dot spacers 15 are provided at (almost) equal intervals on the second transparent resistive film 13 on the second transparent film 14. The spacers 15 are used to avoid contact between the transparent resistive films 12 and 13 in the non-input state.
The third transparent resistive film 16 is also one transparent conductive film made of the same material, similarly to the first and second transparent resistive films 12 and 13. The film 16 is entirely disposed on the lower surface of the second transparent film 14 and has a uniform thickness.
The fourth transparent resistive film 17 includes a transparent conductive film made of the same material, similarly to the first to third transparent resistive films 12, 13, and 16. The film 17 is entirely provided on the upper surface of the glass substrate 18, which will be described below.
The glass substrate 18 is a glass substrate forming the bottom portion of the touch plate 100 and/or a hard plastic, for example. Disposed entirely on the glass substrate is a fourth transparent resistive film having approximately a uniform thickness.
The second dot spacers 19 are provided at equal intervals on the fourth transparent resistive film 13 on the glass substrate 18. The spacers 19 are used to avoid contact between the transparent resistive films 16 and 17 in the non-input state.
The intensity of the pressure of the pen or finger (press) can be adjusted according to the interval of the dot spacers 15 and 19.
The touch panel of the present invention as shown in fig. 7 includes two layers, i.e., layer a and layer B described above. Layer a is considered to be the first touch plate for finger input and includes as its bottom a thin film instead of a glass substrate. Layer B can be considered as a second touch pad for pen input and comprising a glass substrate as its bottom.
Fig. 8 shows in block diagram form the configuration appearance constituting the touch panel input device 100 according to the first embodiment of the present invention. The device 100 shown in fig. 8 includes a touch panel 21, a touch panel controller 22, a controller 23, and a display section 24.
The touch panel 21 is a transparent touch panel constructed as shown in fig. 7. The touch panel 21 is placed on the display portion 24 as will be described below. As a result, the user can visually check the information displayed on the display section 24 through the touch panel 21.
The touch panel controller 22 manages layer a and layer B of the two-layer touch panel 21 in which layer a and layer B are independently controlled. For example, the controller 22 reads the coordinate position pressed by the pen or the finger (fingertip).
The controller 23 manages the operation of the touch pad input device and includes a Central Processing Unit (CPU) and a memory (not shown). The controller 23 reads out a control program from the memory to manage the entire operation of the touch panel input device and executes the program by the CPU to realize the control operation. That is, the controller 23 is connected to the display section 24 to change the contents displayed on the display section 24 in accordance with the input coordinate data read out by the touch panel controller 22.
The display section 24 is a display unit for displaying various data items in response to a control instruction from the controller 23 and includes, for example, a Liquid Crystal Display (LCD). The display portion 24 in the illustrated embodiment may display a selection screen selected by the user and/or a screen containing notification information associated with the user.
Fig. 9 shows a configuration profile of a touch panel controller in the touch panel input device as the first embodiment of the present invention. The structure shown in fig. 9 includes a touch pad controller 22 coupled to a first touch pad 21a including first and second transparent resistive films corresponding to layer a shown in fig. 7. The touch panel controller 22 includes analog switches 31 and 32, a/D converters 33 and 34, and analog switches 35 and 36.
The second touch plate 21B, which includes third and fourth transparent resistive films associated with layer B in fig. 7, is also connected to a touch plate controller 22. The controller 22 also includes analog switches 41 and 42, a/D converters 43 and 44, and analog switches 45 and 46.
Under the management of the controller 23 shown in fig. 8, the touch panel controller 22 can control the peripheral circuits of the touch panel 100 independently of the first touch panel 21a of the layer a and the second touch panel 21B of the layer B.
Fig. 10 shows an example of an image displayed on a display portion of the touch panel input device constructed according to the present invention as a first example of the present invention. The display image shown in fig. 10 is a selection screen related to yes and no existing on a display portion including an LCD or the like. By touching a desired item of "yes" or "no" via the touch panel, the user can input data related to the desired item.
Fig. 11 shows, in cross-section, a state in which data is input from the touch panel input device of the first embodiment using a finger. As can be seen from fig. 11, the first transparent film 11 of the layer a is bent by pressing with a finger, with the result that the first transparent resistive film 12 and the second transparent resistive film are in contact with each other. However, the third transparent resistive film 16 is supported by the dot spacers 19, and therefore the third transparent resistive film 16 cannot be brought into contact with the fourth transparent resistive film in the layer B by pressing with a finger. That is, the films 16 and 17 are kept in a separated state from each other.
When the device is dedicated to finger input, the controller 23 shown in fig. 8 receives information indicating the presence or absence of contact between the films 12 and 13 of layer a from the touch panel controller 22. When the contact is present, the controller 23 additionally receives coordinate information of the contact point. Based on the coordinate values, the controller 23 determines a selected one of a plurality of options existing on the display section 24, such as "yes" or "no" shown in fig. 10. Based on the result of this determination, the controller 23 displays a screen image and performs post-processing.
As described above, when the device 100 is exclusively used for finger input, the device 100 can be used for a finger input touch panel in the same manner by the contact state between the receiving layer a transparent resistive films 12 and 13.
Fig. 12 shows, in a sectional view, a state in which data is input with a pen in the touch panel input device, as described in the first embodiment. The operation of drawing an image on the touch panel 21 using a pen and inputting coordinates related to the image to the touch panel input device will be described with reference to fig. 12.
In fig. 12, when a pen presses the first transparent film 11 of the layer a to input data, the film 11 is bent, and the first transparent resistive film 12 and the second transparent resistive film 13 are brought into contact with each other. Further, the third transparent resistive film 16 and the fourth transparent resistive film 17 come into contact with each other.
When the device is dedicated to pen input, the controller 23 shown in fig. 8 receives information indicating the presence/absence of contact between the films 16 and 17 of layer B from the touch panel controller 22. When there is a touch, the controller 23 also receives the coordinates of the touch point. In the pen input mode, even when a part of the hand touches the touch panel surface as shown in fig. 13, the controller 23 can appropriately control the operation using the input coordinates of layer B instead of the input coordinates of layer a. Therefore, only the coordinates related to the pen input can be received without error.
When the device is dedicated to pen input, even if a finger erroneously touches the touch pad, no input error occurs because the touch of the finger causes only the contact of the layer a.
An operation of automatically determining whether input on the touch panel 21 is performed with a finger (fingertip) or a pen in the touch panel input device constructed in accordance with the first embodiment of the present invention will be described below.
Fig. 14 is a plan view showing an example of display of a virtual keyboard existing on a display portion in an input operation for automatic determination. In fig. 18, when a finger is sensed on one specific character displayed in the virtual keyboard, the transparent resistive layer of layer a is in a contact state. When the pressing by the pen is detected, the transparent resistive layer of the layer a and the transparent resistive layer of the layer B are in a contact state.
Accordingly, in the automatic determination of the finger or pen input, when the controller 23 detects the contact state in the layer a of the touch panel 21 and does not detect the contact state in the layer B, the controller 23 may determine that the data is input with the finger. When the contact state in the layer a and the contact state in the layer B of the touch panel 21 are detected, the controller 23 may determine that data is input using the pen.
An input operation performed by displaying the virtual keyboard shown in fig. 14 on, for example, the display section 14 will be described in detail below. In fig. 14 to 16, japanese characters are used only for explaining the present invention. The invention is not limited to said characters. The key dimensions of the virtual keyboard on the display portion are, for example, approximately 5 millimeters (mm) by 5 millimeters (mm). This size is too small for finger input operation. That is, only a selected one of the keys cannot be correctly pressed with a finger, and thus, the user must use the pen.
When inputting data through the virtual keyboard using a pen, the controller 23 automatically determines a pen input operation according to the above conditions, and then receives the coordinates of the contact point between the transparent resistive films of layer B in the touch panel 21. Based on the coordinates, the controller 23 identifies the key pressed by the pen and then enters the appropriate character into the device.
When a finger is used to touch the virtual keyboard, the controller 23 automatically determines a finger input mode as described above, and then receives the coordinates of the contact point between the transparent resistive films of layer a in the touch panel 21. The controller 23 divides the image of the virtual keyboard into 4 sections or zones as shown in fig. 15 to identify in which of the zones the coordinates belong to the image.
After the area of the touch point has been identified, the controller 23 controls the display section 24 to display a magnified image of the appropriate area, as shown in fig. 16. When the coordinates belong to a plurality of 4 sections or areas, the controller 23 controls the display section 24 to display a certain number of coordinates belonging to the sections or areas in an enlarged (or reduced) manner in the following order.
In the virtual keyboard shown in fig. 16, the size of each key is about 10mm × 10 mm. The dimensions allow for proper operation of the finger. The user performs the desired operation again using the enlarged keyboard image. The controller 23 obtains the touch point coordinates of layer a of the touch plate 21.
Based on the coordinates thus obtained, the controller 23 recognizes the key pressed in the virtual keyboard shown in fig. 16 and inputs a finally recognized one character to the device. When the character is completely input, the display section 24 displays the image shown in fig. 14 again. The processing proceeds to a state of waiting for the next input operation by the fingertip or the pen.
Second embodiment
A second embodiment according to the present invention is given below. It is assumed that the second embodiment includes a similar structure to that of the first embodiment of the present invention.
The second embodiment is a handwriting image input apparatus using a touch panel. As described in conjunction with the first embodiment, the touch panel input device of the present invention can determine a finger input operation and a pen input operation.
When it is determined that the pen input operation is performed, the touch pad input device of the second embodiment receives the touch point coordinates of the touch pad layer B shown in fig. 7, similar to the first embodiment. In the second embodiment of the touch pad input device, points corresponding to the coordinates received from the touch pad 21 are drawn on the display section 24. Therefore, as shown in fig. 17, by drawing a figure on the touch panel 21 with a pen, an image of the handwritten figure can be displayed on the display section 24.
When the touch panel input device of the second embodiment determines that data is input with a finger, coordinates are received from layer a of the touch panel shown in fig. 7, as in the first embodiment. In operation, the second embodiment clears a circle on the display portion 24 with a radius of approximately 5mm from the point corresponding to the received coordinates.
As a result, by moving a finger (fingertip) on the touch panel, the displayed image can be erased on the display portion 24 as shown in fig. 18. In the area within the dotted line indicated by Q in fig. 18, the displayed image has been erased by moving the fingertip.
That is, a desired graphic can be drawn on the display portion 24 with the pen. When it is desired to erase a portion of the graphic, the user simply moves the fingertip over the portion of the display desired to be erased. The touch panel input device can thus be used as an image input device that can be used as a blackboard.
Third embodiment
The third embodiment of the present invention is described below
Fig. 19 shows in cross-section the configuration profile of a third embodiment of a touch pad input device according to the invention.
The structure of fig. 19 includes a touch pad input device 200 as a third embodiment according to the present invention. Like the first and second embodiments, the third embodiment mainly includes two layers, i.e., layer a and layer B.
The third embodiment differs from the first and second embodiments in that the second transparent film 14 shown in fig. 7 is constituted by two independent transparent films 14a and 14 b.
Thus, layers a and B are contact pads that are electrically and/or structurally completely independent of each other. By simply attaching two contact pads to each other, a device similar to the one described for the first and second embodiments can be constructed.
With regard to the touch panel of layer B shown in fig. 19, a general touch panel of the prior art can be obtained. In the layer a touch panel of fig. 19, only the material of the bottom changes from glass to a thin film. It is possible to directly use the related art touch pad production process and thus to reduce the original production cost and increase the production rate.
The above-described embodiments are the best embodiments of the present invention and may be changed and modified within the scope of the present invention.
As can be understood from the above description, in the touch panel input device of the present invention including two touch panels attached to each other, when inputting a position using a finger (fingertip) or a pen, information of the position indicated by the fingertip or the pen can be appropriately detected within any one time period.
In the touch panel input device of the present invention, when a position is input, whether the input operation is performed by a finger or a pen can be automatically recognized according to the received pressure. Therefore, even if the erroneous input is caused by, for example, touching the touch panel with a hand in the pen input mode, the apparatus can perform a control operation to appropriately reject the erroneous input.
With the touch panel input device of the present invention, a related art touch panel production process can be used as the production process. This reduces the original cost and improves the productivity.
While the present invention has been described in connection with the specified embodiments, it is not to be restricted by the embodiments but only by the appended claims. It will be apparent to those skilled in the art that changes and modifications may be made to the described embodiments without departing from the scope and spirit of the invention.
